The deployment of Thaad "does not help addressing the security concerns of relevant countries", Geng Shuang, a spokesman for China's foreign ministry, said at a briefing in Beijing on Wednesday.
Russian Federation and China opposed the deployment of the Terminal High Altitude Area Defense (THAAD) system, as both say it has the potential of fueling an arms race. The South's defence ministry confirmed on Wednesday the launchers would be installed on a former golf course near Seongju City some 217 km (135 miles) south of Seoul.
A THAAD battery normally consists of six launchers capable of firing up to 48 interceptor missiles, but only two launchers have been operational so far.
The placing of additional THAAD launchers will likely trigger an angry response from area residents and activists who have opposed the system. Seongju residents and activists have anxious over rumoured health hazards and the possibility of being targeted in North Korean attacks.
Putin called for all parties with a stake in the stability of the Korean Peninsula to support the Russian-Chinese road map, which involves resuming talks that would bring North Korea, China, Russia, Japan, South Korea and the U.S.to the negotiating table.
Moon added that the situation could become unpredictable if North Korea did not halt its provocative actions, according to a Russian translation of his comments in Korean to Putin. But Putin insisted the road map offered "a practical way, as we see it, to ease tensions and to move gradually toward a settlement on the peninsula".
North Korea has pledged to take "powerful counter measures" to respond to United States pressure or any new sanctions against it over its missile program, accusing Washington of wanting war.
US Ambassador to the United Nations Nikki Haley accused the North Korean leader of "begging for war".
"North Korea has posed a challenge to the worldwide community, turning into an unprecedented, serious and urgent threat", Abe said, recalling that on August 29 Pyongyang launched a ballistic missile that flew over Japan's territory.
"It's impossible to scare them", Putin said of North Korea.
Putin made the remarks Wednesday after meeting with South Korean President Moon Jae-in in Vladivostok, Russia.
Following Pyongyang's test on Sunday, Abe spoke to Putin over the phone, and reminded him of the important role Russian Federation can play as a permanent member of the United Nations Security Council in reigning in North Korea. But after North Korea conducted its second flight test of a developmental intercontinental ballistic missile in July, Moon ordered his military to work with US commanders in South Korea to temporarily place more launchers before the reviews are conducted.
The clashes came as South Korean President Moon Jae-in and Japanese Prime Minster Shinzo Abe met in eastern Russian Federation and repeated their calls for stronger punishment of North Korea over its nuclear ambitions, including denying the country oil supplies.
When Putin visited Japan for the first time in 11 years last December, the two leaders said they would negotiate the legal mechanisms required for holding joint economic activities, and that such agreements would not harm the political positions of the two countries.
Pyongyang appears determined to continue its nuclear bomb and missile tests until it is confident it could strike the United States, while Trump - who spoke with Malcolm Turnbull this morning - is committed to stopping Kim Jong-un's progress.
Putin said he had invited Abe to attend the St Petersburg International Economic Forum (SPIEF) in 2018, "and Shinzo accepted our invitation".
He told reporters before his departure from Japan that "We must make North Korea understand there is no bright future for the country if it pursues the current path".
